Residents of the state have been on edge in recent weeks amid ongoing nuclear and ballistic missile tests by North Korea.

The hermit nation tested an ICBM last fall that experts believe has the range to strike Hawaii and other U.S. states.

Other residents sought shelter in various places.

The Federal Communications Commission announced Saturday it will be conducting a full investigation into the incident. The agency has jurisdiction over emergency broadcast systems.

Hawaiian Gov. David Ige said the mistake was human error, adding that a worker pushed the “wrong button” at shift change.
